Support, Can you please assist in getting our four servers to connect to the Licensing servers. I have run through all trouble shooting on each of the following forum pages: [https://www.wowza.com/docs/troubleshoot-wowza-streaming-engine-licensing-errors-at-startup](https://www.wowza.com/docs/troubleshoot-wowza-streaming-engine-licensing-errors-at-startup) Cannot get a ping response or telnet connect prompt [https://www.wowza.com/docs/how-to-configure-wowza-media-server-to-use-proxy-server-to-communicate-with-license-server-](https://www.wowza.com/docs/how-to-configure-wowza-media-server-to-use-proxy-server-to-communicate-with-license-server-) How-to-configure-Wowza-Server-to-use-proxy-server-to-communicate-with-license-server I input our proxy config in the file and tired both a No-Auth and Auth configuration We have approved communication for the following locations through our proxy, but I am still getting the error in the log file.

ERROR server comment 2013-09-30 08:49:09 -0.987 system.exit[2] Open Questions: 1. Is there something you will have to do on your side to authorize our servers to communicate? Will you need our IP’s to add to a white list? 2. Is the response a separate transaction initiated by the vendor or a simple response to your outbound connection? 3. Can I designate/purchase a perpetual license that doesn’t require communication to the Wowza License Servers? ---

Did you try adding the inbound rule, as mentioned in your other posts? 1. No, nothing like that is required on the Wowza side. 2. I think it is just a response, but you will probably have to add the inbound rule 3. I would continue trying to make the proxy work, try adding the inbound rule. Richard ---

You had asked if an inbound rule is also necessary in your other post today, right? I am supposing that you will have to do that. In any case, that is what I would try. I believe that is necessary. Richard ---

This issue was resolved in ticket #68215. The problem was a proxy configuration on the user side. It is important that the correct IP address of the proxy server is listed in the proxy configuration as described in this article: [How to configure Wowza Media Server to use proxy server to communicate with license server](https://www.wowza.com/docs/how-to-configure-wowza-media-server-to-use-proxy-server-to-communicate-with-license-server). In this case, the user had prepended the proxy setting with an “http:” and was providing an incorrect, internal proxy setup URL. Once the correct proxy IP address and configuration were validated on their side, the issue was resolved. -Tim ---

I missed the inbound rule, what post was that in? Can you send me the link or information required for the inbound rule? ---

I am in need for a solution which doesn’t require internet connection. Is such a licensing scheme possible? Please reply ASAP. ---
